I have a multi-threaded, high-performance and long-running process (I mean hours) in Spring. In order to allow this process to cancel I like to check periodically for the permission to cancel this process using a huge SQL.

@Service
public class CancelHolder {
  @PersistenceContext
  private final EntityManager em = null;

  public boolean isCancel() {
    return !em.createQuery("..<huge sql>..").getResultList().isEmpty();
  }
}

This isCancel is called about 20/sec/thread from about 100 threads make a total of 2000 calls per second.

Problem

If I use @Cacheable(value="cancelcache", sync=true) the method is called once and stored forever.

Solution

I have to evict the cache every 1 second.

Question

How to evict the cache every 1 second?

That depends on the underlying cache provider. Do you simply use the default one? – jAC Apr 17 '22 at 07:29
@jAC Yes. I do. – Grim Apr 17 '22 at 07:35
